well as far as my opinion goes I'm more in favour of the manga only because it seems that the overall series is more developed and was more "good"...but with that in mind I guess the best advantage that the anime have that the manga (naturally) does not have and that is better animation..but yea overall I would say the manga here =x

The manga is much better, but then again, the anime pretty much follows the manga exactly (w/less nudity) till the last episode.. So you might just want to watch the anime then skip "x" number of chapters in the manga till you find the spot that the anime leaves off at.
